Well I got my Paperwhite, I am in the UK. I had a Kobo Glo which I took back so I can compare. I am happier with the Amazon eco system etc. so the experience seems better. The Paperwhite in the case is a lovely device. The screen with the light on lowest setting looks like a normal e-ink screen so great. With the light on 7 in a lit room it compares well with the Kindle Keyboard. The light on full looks rough with a brighter LED on the left and a red blotch and a green blotch. To be honest I can't see me using full brightness. In a normal room I will use it as if it was a Touch ignoring the light.
I might report it to Amazon to change after Christmas, I don't want the hassle of swapout now or risk getting a worse one.
